Overview
ROL, or rotate-left, is a bit operation that shifts bits around within a value while wrapping the overflowed bits back into the result.
Bit rotations move bits within a value rather than encrypting data in a high-level sense. They are often used inside custom encoding routines, lightweight protection logic, and challenge binaries because they make raw bytes harder to read while remaining reversible.
In this lab, you practice following custom transformation logic, recognizing rotate operations, and reconstructing protected data from low-level behavior.
